I lost my cat 2 years ago, and he was gone for 10 days. Miraculously he came back! After that, I looked for a solution in case it happened again, and I came across your Bluetooth tracker.
He tried to run away for the second time during our move and this time we were able to find him immediately with Chipolo :)
I cannot live without Chipolo now, our other cat also has a Chipolo now ^^
